WARNING! Always make sure conditions are safe before walking on the ice.
WARNING! This device should not be used as a navigational aid to prevent
collision, grounding, boat damage, or personal injury. When the boat is moving, water
depth may change too quickly to allow time for you to react. Always operate the boat
at very slow speeds if you suspect shallow water or submerged objects.
WARNING! The electronic chart in your Humminbird unit is an aid to navigation
designed to facilitate the use of authorized government charts, not to replace them.
Only official government charts and notices to mariners contain all of the current
information needed for the safety of navigation, and the captain is responsible for
their prudent use.
WARNING! Humminbird is not responsible for the loss of data files (waypoints,
routes, tracks, groups, recordings, etc.) that may occur due to direct or indirect
damage to the unit’s hardware or software. It is important to back up your control
head’s data files periodically. See your control head operations manual for details.
WARNING! Disassembly and repair of this electronic unit should only be
performed by authorized service personnel. Any modification of the serial number or
attempt to repair the original equipment or accessories by unauthorized individuals
will void the warranty.
NOTE: Some features discussed in this manual require a separate purchase. Every
effort has been made to clearly identify those features. Please read the manual
carefully in order to understand the full capabilities of your model.
NOTE: The illustrations in this manual may not look the same as your product, but
your unit will function in a similar way.
NOTE: To purchase accessories for your control head, visit our Web site at
humminbird.com or contact Humminbird Technical Support at 1-800-633-1468.

without notice. This manual was written in English and may have been translated to
another language. Humminbird is not responsible for incorrect translations or
discrepancies between documents.
NOTE: Product specifications and features are subject to change without notice.
NOTE: Humminbird verifies maximum stated depth in saltwater conditions, however
actual depth performance may vary due to transducer installation, water type, thermal
layers, bottom composition, and slope.

secure the depth collar in place.
• Slide the top depth collar down to secure the MEGA Live ICE adapter base to
the desired height, and tighten the knob to secure the depth collar in place.
NOTE: The MEGA Live ICE Imaging transducer must be submerged below
the ice.
NOTE: Periodically check that the adjustable depth collars are secure and
tighten if necessary.
5. Remove the nut from the third depth collar and slide the collar over the cables
and shaft (orientation of the flat end does not matter for this depth collar).

4. Connect the Heading Sleeve and Cap
1. Slide the heading sleeve over the cables and shaft and align the holes in the
sleeve with the holes at the top of the shaft.
NOTE: Align the heading sleeve so that the raised section faces away from
the MEGA Live transducer’s pinging element (instead of towards it) to ensure
the arrow on the heading cap will point in the same direction as the MEGA Live.
2. Slide the heading cap over the cables and heading sleeve. The gap in the
heading cap should align with the raised section of the heading sleeve (see the
illustration Connecting the Heading Sleeve and Cap).
